Please note: If you wish to make a few bags from Charlie’s Aunt sewing patterns or books to sell, please read the rules in the "additional information" section of our policies page.

This is a PDF sewing pattern for the Caistor Courier Bag. With a simple utilitarian feel, this style takes its inspiration from the practical courier bags of the wartime years.
A good size and shape, the Caistor Courier takes on a nautical feel when made in cotton canvas, denim and ticking stripes. Or create in corduroy or tweed for a quintessentially vintage English country look. Make plain with a single flap or with a double mock flap. Caistor Courier has a back pocket and the template doubles as an interior pocket.

The bag’s finished dimensions are: Height 15” (38cm) and width 15” (38cm), with the width at the base approx. 2” (5cm). The strap length is 38” (96cm).

This PDF has 18 pages—10 pages including the cover, general, cutting out and step-by-step instructions, and 8 pattern sheets with the templates, which you must print and cut out. All of the templates are actual size. As some of the templates are too big to fit on one sheet, you must cut out and tape these templates together where shown. Instructions for this are clear.

¾ yard (70cm) of 58” (148cm) wide, or 1 yard (95cm) of 44” (112cm) wide exterior fabric

Important Copyright Information:

Although all of my patterns and books are covered by the copyright and patents act, I realise that several of my customers would like to be able to make a few items from my patterns to sell, so I have decided to allow it again, as long as they stick to the following rules:

* Make no more than 10 bags in a year to sell from any one Charlie’s Aunt pattern, and up to a MAXIMUM of 40 bags in total from a combination of any of my patterns in a year. Please don’t make any more than this – I have more than 20 different sewing patterns and it simply wouldn't be fair to buy 15 and make 10 of each, because you would be adopting my entire concept that way. If you intend to make any more than 40 in a year, this would be deemed a big business and would be totally against the rules. Please respect this!

* Write on each swing ticket and in all Etsy/online descriptions the following words: “This bag was made using a Charlie’s Aunt sewing pattern designed by Emma Brennan”. A link to my Etsy shop would also be greatly appreciated. Please don’t put your own designer labels in my designs – that isn’t fair!

* Please have the courtesy to drop me a line to ask if you can make the bags to sell. This way I can keep track of who’s doing what and I can hopefully persuade you to share photos of the bags you make on the Charlie’s Aunt Facebook site.

* All items for sale must be handmade by you. Contracting with others to mass produce Charlie’s Aunt designs is STRICTLY PROHIBITED.

* Distribution of the pattern pieces and corresponding instructions is STRICTLY PROHIBITED. Please do not copy my patterns in any way. The words, diagrams and pictures are covered by copyright and I will pursue anyone who infringes this.

* Finally, please be respectful my designs and policies. Being allowed to make a limited number of bags from my patterns to sell is a privilege and not a right.

Please email me at if you have any questions


The PDF patterns contain instructions, illustrations, photographs and pattern templates for one style of bag, purse or fashion accessory. The templates are full size and can be printed on A4 paper, but some templates need to be joined together with tape because they are too big to fit on one page. All patterns contain detailed instructions on how to cut and join pattern templates.
